Abstract

The MSITs(Minimum Spontaneous Ignition Temperatures) or AITs(Autoignition Temperatures) describe the minimum temperature to which a substance must be heated, without the application of a flame or spark, which will cause that substance to ignite. This study measured the MSITs(Minimum Spontaneous Ignition Temperatures) of n-pentanol+ethylbenzene system by using ASTM E659 apparatus. The MSITs of pure n-pentanol and ethylbenzene were $285^{\circ}C$ and $475^{\circ}C$, respectively. The experimental MSITs of n-pentanol+ethylbenzene system were a in good agreement with the MSIT calculated by the proposed equations with a few A.A.D.(average absolute deviation).

최소자연발화온도는 가연성혼합물이 화염이나 스파크 없이 주위로부터 충분한 열에너지를 받아서 스스로 발화하는 최저온도를 말한다. 본 연구에서는 ASTM E659 장치를 이용하여 가연성 혼합물인 n-Pentanol+Ethylbenzene계를 구성하는 순수물질과 혼합물의 최소자연발화온도를 측정하였다. Pentanol과 Ethylbenzene의 측정된 최소자연발화온도는 각 각 $285^{\circ}C$, $475^{\circ}C$ 였다. 그리고 n-Pentanol+Ethylbenzene 계의 예측된 최소자연발화온도는 실험값과 적은 평균절대오차에서 일치하였다.
